In 2018, Fisher Space Pen, the iconic “astronaut pen” celebrates #FiftyYearsInSpace, having flown for the first time on NASA’s Apollo 7 Mission in October, 1968. The Apollo 7 Mission is a historic First in many respects: First Manned Space Flight of NASA’s Apollo Program; First time a Saturn IB vehicle flew into space; First three-person American space mission; First space mission to include a live TV broadcast from an American spacecraft; and the first time astronauts began using the newly-developed Fisher AG7 Anti-Gravity Space Pen.

When manned space missions began, astronauts used pencils to write in outer space.  But the lead often broke and became a hazard floating in the capsule’s atmosphere, possibly causing a short in an exposed electrical connection within the spacecraft. Since the fire on Apollo 1, in which three astronauts lost their lives, NASA required writing instruments that would not burn in a 100% oxygen atmosphere.
Paul Fisher, who was president of Fisher Pen Co., had been manufacturing ball point pens since 1948.  When he heard John Kennedy’s challenge to land a man on the moon by the end of the decade, he started thinking about how ordinary ballpoint pens would have trouble writing in space, but if a pen could be sealed and pressurized, it would keep the solvents from evaporating in the gravity-free vacuum of space and would also provide a reliable ink supply to the pen point. In 1966, after several years and many experiments, Fisher successfully developed the first pressurized pen.

The Fisher Space Pen Pressurized Ink Cartridge enables the free-flow of ink in zero gravity. It writes upside down, as well as under water and over almost any surface, in extreme temperatures (-30 to +250 degrees F), and three times longer than the average pen.
Fisher sent his Space Pen samples to Dr. Robert Gilruth, Director of the Houston Space Center. The Fisher Space Pen was thoroughly tested by NASA and passed all tests. NASA began using the Fisher AG-7 Anti-Gravity Space Pen on the Apollo 7 Mission in October 1968.  Click here to read the History of Fisher Space Pen.
Fisher Space Pens were continuously used during NASA’s Space Shuttle Program Missions as well as on the Mir Space Station and are still used onboard the International Space Station and all manned space flights today. Fisher Space Pen is an iconic symbol of American technology and classic design. Its popular Bullet Space Pen is in the permanent collection of the Museum of Modern Art in New York and was also featured in an episode of the hit series “Seinfeld” entitled “The Pen.”
